For the beginners

Before we understand C&C++, we should be very clear about the purpose of doing this course. After the completion of the above mentioned course we will be able to make softwares and operating system [UNIX is an operating system made in C].

Now he question arises what are softwares and operating systems?

Softwares are programs which makes it easy for human to instruct a machine in his own language and get the work done out of it.

For eg- we all are familiar with ATM machines, when a person takes out money from an ATM machine , he simply follows the instruction coming on the machine screen and in few minutes he gets his desired amount. Now ,if the person is not a computer literate ,he may think that machine has understood his language but the fact is that the machine has a software(program) installed in it which converts the human language in machine language and make the machine hardware(parts) work according to his instruction.

In computer language if we discuss softwares we can talk about MS-office, excel, powerpoint, paint etc, they are programs designed to serve various purposes like Office for document making, excel for tabular charts, powerpoint for advertisement, poster etc designing and paint for drawing. There are programs like media player which are used to play music and movies. So in nutshell we can say that these are programs which are made by human to instruct the computer hardware to serve various purposes.

Now if talk about operating system, it is a system software which makes the computer hardware run according to human desire. For eg-MS-DOS, WINDOWS-98,2000,Xp,VISTA; LINUX, UNIX etc.

So now we are ready to start with C and C++.
